Command History
Usage Guidelines This command enables you to attach multiple clients to a single 802.1X-enabled port. In this mode, only one
of the attached hosts must be successfully authorized for all hosts to be granted network access. If the port
becomes unauthorized (re-authentication fails, or an Extensible Authentication Protocol over LAN
[EAPOL]-logoff message is received), all attached clients are denied access to the network.
Examples This example shows how to enable 802.1X on Fast Ethernet interface 0/1 and to allow multiple hosts:
Switch(config)# interface fastethernet0/1
Switch(config-if)# dot1x port-control auto
Switch(config-if)# dot1x multiple-hosts
You can verify your settings by entering the show dot1x [interface interface-id] privileged EXEC
command.
